NOTE: If the charger has to provide its maximum maintain current (1.8A) for a continuous 12 hour period, it will go into Abort Mode (see Aborted Charge section). This is usually caused by a load on the battery, or the battery could be bad. Make sure there are no loads on the battery. If there are, remove them. If there are none, have the battery checked or replaced.

MAINTAINING A BATTERY

This unit maintains both 6 and 12 volt batteries, keeping them at full charge. It can charge small batteries and maintain both small and large batteries. If you are maintaining a fully charged large battery, you are properly utilizing the battery charger. However, if you use this battery charger to charge a large battery, such as a marine deep-cycle battery that was not fully charged, you may not get the battery’s full capacity. Therefore, we do not recommend charging a large battery with this unit. NOTE: The maintain mode technology allows you to safely charge and maintain a healthy battery for extended periods of time. However, problems with the battery, electrical problems in the vehicle, improper connections or other unanticipated conditions could cause excessive current draws. As such, occasionally monitoring your battery and the charging process is required.

BATTERY CHARGING TIMES

Times are based on a 50% discharged battery and may change, depending on age and condition of battery.

DESULFATION MODE

If the battery is left discharged for an extended period of time, it could become sulfated and not accept a normal charge. If the charger detects a sulfated battery, the charger will switch to a special mode of operation designed for such batteries. If successful, normal charging will resume after the battery is desulfated. Desulfation could take up to 8 hours. If desulfation fails, charging will abort, the red LED will light, and the display will scroll “CHARGE ABORTED-BAD BATTERY”.

ABORTED CHARGE

If charging cannot be completed normally, charging will abort. When charging aborts, the charger’s output is shut off, the red LED will light, and the display will scroll “CHARGE ABORTED-BAD BATTERY”. Do not continue attempting to charge this battery. Have it checked or replaced.
